WTF...

BERLIN (Reuters) - A Berlin grandmother who has worked the city's diplomatic quarter as a prostitute for the last 49 years plans to retire when she turns 64 next year, according to Germany's Bild newspaper.[...]

"I've got a lot of regular clients," the blonde woman told the newspaper, pictured wearing a short red mini skirt and high-heeled white boots as she stood near the Japanese embassy. She said she charges 30 euros ($36) and on good nights she has four to five clients.

"I'm going to stop at 64 and retire," said Dolle, whose husband drops her off for work each night after the television evening news and who has a nine-year-old granddaughter.

I have emphasized all the WTF parts of the story...I don't think I need any further explanation. A little bit of math and common sense will get you through it.
